I recently got a HP Spectre x360 13-ap0043dx
I am a lucky man. My "HP Spectre 13-af006ur" still supports PS/2 as a fallback option :-) But, unfortunately, the primary interface is SMBUS so I can't test any I2c stuff with it.
The touchpad is a Synaptics I2C-only (meaning no PS/2) model and I am unable to tap or click.
Tap failing is expected as according to your dmesg, touchpad is running in polling mode where fingers release events are lost very often at my experience.
Try add following snippet to ig4iic_pci_methods array in
/usr/src/sys/dev/ichiic/ig4_pci.c and rebuild kernel or ig4.ko
/* Bus interface */
DEVMETHOD(bus_setup_intr, bus_generic_setup_intr),
DEVMETHOD(bus_teardown_intr, bus_generic_teardown_intr),
DEVMETHOD(bus_alloc_resource, bus_generic_alloc_resource),
DEVMETHOD(bus_release_resource, bus_generic_release_resource),
DEVMETHOD(bus_activate_resource, bus_generic_activate_resource),
DEVMETHOD(bus_deactivate_resource, bus_generic_deactivate_resource),
DEVMETHOD(bus_adjust_resource, bus_generic_adjust_resource),
DEVMETHOD(bus_set_resource, bus_generic_rl_set_resource),
DEVMETHOD(bus_get_resource, bus_generic_rl_get_resource),
The initial goal is to get "iichidX: allocated irq at 0xXXXXXXXXXXXXXX and rid 0" string in dmesg output instead of "iichidX: IRQ allocation failed. Fallback to sampling."

Unfortunately, I still have an issue even with your patch:

iichid1: IRQ allocation failed. Fallback to sampling.
It is still in polling mode. Most probably it requires GPIO interrupt support which is not done for FreeBSD yet.
sysctl dev.iichid.1.sampling_rate=125 should help to some extent, but I doubt that it solves the problem entirely. I will try to create a workaround to the problem but it will take some time.
About clicks: Could you post here evdev capabilities of your touchpad. They can de obtained with evemu-record tool of devel/evemu port

sysctl dev.iichid.1.sampling_rate=125 doesn't help for me. You're probably right, the touchpad uses GPIO interrupts. However, take your time, there's no rush.
Luckily, I just got my USB-C mouse today (I live in New York, US) so I can use FreeBSD on my laptop while I wait for the touchpad to be fully supported. The USB-A port is used by a Wi-Fi dongle (well, the Intel AC 9560 Wi-Fi isn't supported either, but then this isn't some refurbushed 5-year-old ThinkPad with the advantage of years of support).

Your recent commits have fixed the issue. Thank you!
Even if it's not as good as Windows, Linux, or OpenBSD, doubling the sampling rates also helps with the accuracy/precision of clicks (on my Spectre):
dev.iichid.1.sampling_rate_fast=120
dev.iichid.1.sampling_rate_slow=10
I'm closing this ticket.
